Eagle Services Asia Pte Ltd (ESA) is a joint venture between Pratt & Whitney and SIA Engineering Company. The combination of these two leading organizations since 1998 has enabled ESA to establish itself as one of the largest aircraft engine MRO companies in Singapore, a strategic part of Pratt & Whitney’s Global Service Partners (GSP) network and a key Pratt & Whitney Center of Excellence for the PW4000 Engine Series.

Pratt & Whitney Centre of Excellence for PW4000 Engine Series

With more than 900 employees and a capacity to overhaul 300 jet engines annually, ESA’s nearly 300,000 square feet facility strategically located adjacent to Changi International Airport has state of the art modern assembly lines and world class repair capabilities.

A variety of services are offered at ESA including engine overhaul, heavy maintenance, hot section refurbishment, module repair, inspection, performance enhancements, engine testing and field support. Leveraging on lean manufacturing tools, ESA has extensive in-house maintenance, repair and overhaul capabilities for the following engines:

PW4000 94”

The 94-inch-fan PW4000 engine is the first model in Pratt & Whitney's high-thrust family for large aircraft. It covers a range of 52,000 to 62,000 pounds of thrust and has five major aircraft applications. The PW4000 94" power the Boeing 747-400, Boeing 767-200/-300, Boeing MD-11, Airbus A300-600, and Airbus A310-300.

PW4000 100”

Pratt & Whitney designed and built a larger PW4000, with a fan diameter of 100 inches, specifically for the Airbus A330 wide-bodied twinjet. It was Pratt & Whitney's first high thrust derivative, based on the successful 94-inch PW4000 model. The engine is the market leader on the A330, capturing more than half of all engine orders. The PW4000 100" powers the Airbus A330-300 and Airbus A330-200.

PW4000 112”

The 112-inch-fan PW4000 is an ultra high thrust model covering the 74,000 to 98,000 pound thrust class to meet the requirements for the Boeing 777-200/-200ER/-300 twinjets. It was the launch engine for the 777, entering service in 1995.


Pratt & Whitney's JT9D opened a new era in commercial aviation: the high bypass ratio engine to power wide body aircraft. It introduced many advanced technologies in structures, aerodynamics and materials to improve fuel efficiency and reliability. Since entering service on the Boeing 747 in 1970, the JT9D has proven itself to be a workhorse with over 3,000 cumulative engines delivered. The JT9D has flown more than 169 million total hours to date. Each day, more than 600 aircraft takeoffs are accomplished using the JT9D power. Today, the JT9D powers the Boeing 747, Boeing 767, Airbus A300, Airbus A310 and McDonnell Douglas DC-10.


Developed in conjunction with GE Aviation Services, the General Electric GE90 is a family of high bypass turbofan engines built by GE Aviation for the Boeing 777, with thrust ranging from 74,000 to 115,000.

EcoPower(R) Engine Wash

Our EcoPower(R) engine wash system cleans engines right on the tarmac using atomized water in a closed-loop, environmentally friendly system. A cleaner engine cuts fuel burn and extends part life and time on-wing. Eagle Services ASIA is committed to providing product and service solutions that deliver environmental performance and customer value.

Game Changing Revolutionary PurePower® PW1000G

In 2012, ESA will be adding MRO capability for Pratt & Whitney’s game changing revolutionary PurePower® PW1000G engine series. ESA has been designated as the first engine center to service the PW1500G engine, the PurePower® variant that will power the Bombardier CSeries aircraft. The PurePower® PW1000G engine series delivers double-digit improvements in fuel efficiency and emissions with a 50-percent reduction in noise over the current crop of engines. It’s all about lower costs and better environmental performance.
